SubjectRe: 2.6.37-rc7: Regression: b43: crashes in hwrng_register()

All right, 3 dmesg excerpts attached...
2.6.37-rc7-vanilla.dmesg:
2.6.37-rc7 vanilla (i.e. with 84c164a34ffe67908a), crashing
via-rng is registered first, b43-rng second
2.6.37-rc7-without.dmesg:
2.6.37-rc7 with 84c164a34ffe67908a reverted, not crashing
b43-rng is registered first, via-rng second
2.6.37-rc7-without+modprobe.dmesg:
2.6.37-rc7 with 84c164a34ffe67908a reverted, b43 blacklisted and
manually modprobed after via-rng, crashing
via-rng is registered first, b43-rng second

Seems like the crash shows up when b43-rng is registered second, but not
when via-rng is registered second.
Btw.: `cat rng_available' does also not crash when via-rng is registered
second.
